NOTE: When connecting the RJ45 console to the patch panel or terminal server using Cat5e or Cat6 Ethernet cables, the maximum cable length is 100m. However, if the Ethernet cable is disconnected from the patch panel or terminal server but connected to the RJ45 console, the maximum cable length is 6m. If the cable is longer than 6m when disconnected from the panel or server, your switch may not boot.
NOTE: Before starting this procedure, be sure that your PC has a 9-pin serial port and that you have a terminal emulation program already installed and running on the PC.
NOTE: If your PC’s serial port cannot accept a female DB-9 connector, acquire a DB-9 male-to-male adaptor.
  1. Install the provided RJ-45 connector side of the provided cable into the S3048-ON console port.
  2. Install the DB-9 female side of the provided copper cable into your PC’s serial port or into other data terminal equipment (DTE) server hardware that you intend to use.
  3. Keep the default terminal settings on the console as follows:
    • 115200 baud rate
    • No parity
    • 8 data bits
    • 1 stop bit
    • No flow control
